VTI SCP1000 Barometric Pressure Sensor

The VTI SCP1000 is an absolute pressure sensor which can detect atmospheric pressure from 30-120 kPa. The pressure data is internally calibrated and temperature compensated. The SCP1000 also provides temperature data and has 4 measurement modes as well as standby and power down mode.

All that is required to obtain pressure data in kPa or temperature data in degrees Celsius is a single multiplication using constants. Communication is via an SPI bus which also provides additional control lines such as an interrupt line and trigger input.

Features:

• 4 measurement modes plus standby and power down mode
• SPI interface
• Pressure resolution: 1.5 Pa
• Temperature resolution: 0.05°C

Application Ideas:

• Barometric pressure for weather station
• Altimeter for model rocketry
• Pressure chamber sensor
• Cabin pressure sensor (plane/submarine)

Key Specifications:

• Power requirements: 2.4 VDC to 3.3 VDC @ 25 uA
• Communication: SPI Serial Interface (max 500 kHz)
• Dimensions: 0.48 x 1.05 x 0.93 in (12.19 x 26.68 x 23.61 mm)
• Storage temperature: -22°F to +185°F (-30°C to +85°C)
